1 Claim. (Cl. 254*28) The present invention relates to new and useful improvements in staple removers for removing or extractmg staples of a type used for stapling letters or other papers by a conventional ofiice stapling machine.

An important object of the invention is to provide a staple removing tool including a retractable claw adapted for engaging a staple to slide the same rearwardly on a stationary blade adapted for insertion under the top of the staple.

Another object is to provide a retractable claw of a downwardly and rearwardly curved construction and formed with a transverse groove in which the top of the staple is engaged to firmly grip the staple during the removal thereof.

A still further object is to provide a tool of this character of simple and practical construction, which is eflicient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purpose for which the same is intended.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view;

Figure 2 is a longitudinal sectional view taken on a line 2--2 of Figure 1;

Figure 3 is a group perspective view; and

Figure 4 is an enlarged sectional view of the claw taken on a line 4-4 of Figure 1.

Referring now to the drawing in detail, wherein for the purpose of illustration, I have disclosed a preferred embodiment of my invention, the numeral 5 designates a handle composed of a bottom section 6 and a top section 7 and cemented or otherwise suitably secured to each other in superposed relation.

The confronting faces of the top and bottom sections are recessed to form a front cylindrical chamber 8 and a rear rectangular-shaped chamber 9 separated from each other by a partition ltlhaving an opening 11 therein. A passage 12 extends forwardly from the front chamber 8 through the front end of the handle 5.

A cylindrical housing 13 formed of a pair of semicylindrical hollow sections 14 and 15 and closed at each end is placed in the front chamber 8 and a rod 16 is slidably mounted with the rear end of the rod slidable in the opening 11 and has a head or stop 17 secured to the rear end of the rod and is slidable in the rear compartment 9 of the handle.

The front end of rod 16 is flattened, as indicated at 18,

Patented Apr. 10, 1956 and is slidable in the passage 12 at the front end of the handle.

A downwardly and rearwardly curved claw 19 is formed at the front end of the flattened portion 18 of the rod, and the end of the claw is formed with a transverse groove 29. The claw 19 and flattened portion 18 of the rod are enclosed in a cover 21 of rubber or other molded material and is provided at its upper front portion with an upstanding finger grip 22.

The bottom of the bottom section 6 of the handle is flattened, and to the underside a blade 23 is secured by screws or the like 24 with the front end of the blade projecting forwardly under the claw 19 and formed with a downwardly inclined tapered and beveled tip 25.

A coil spring 26 is enclosed in the housing 13 with the rear end of the spring abutting the rear end of the housing 13 and with the front end of the spring tensionally engaging a washer 27 secured to rod 16 immediately behind the flattened front end portion 18 thereof to project the claw 19 forwardly.

In the operation of the tool, the tip 25 of blade 23 is inserted under a staple 28 and with the claw 19 forwardly of the staple, as illustrated in Figure 2 of the drawing. With the handle 5 held in the hand of a person, the thumb engages the finger grip 22 to slide the claw rearwardly whereupon the upper portion of the staple will be engaged in the groove 20 of the claw and further rearward movement of the claw Will slide the staple rearwardly on the blade 23 in a manner illustrated by the dotted lines in Figure 2 of the drawing to thus extract the staple.

Upon releasing the claw 19, the spring 26 will project the same to its forward position.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the ap pended claim.

What is claimed as new is as follows:

A staple remover comprising a handle, a blade at the bottom of the handle and projecting forwardly at the front end of the handle and adapted for insertion under a staple, said handle having an opening at its front end and a front cylindrical chamber and a rear rectangular shaped chamber internally of the handle, a rod slidable forwardly and rearwardly in the opening and having a flattened rearwardly curved claw at its front end overlying the blade, said claw having a transverse groove adapted to engage and pull the staple rearwardly on the blade, :1 cover of substantially rigid molded material enclosing the claw, an upstanding finger grip integrally formed with the cover to slide the claw rearwardly, a coil spring in the front chamber and engaging the rod to project the claw at the front end of the handle, a housing in the front chamber for the spring, and a rectangular shaped head slidable 1n the rear chamber and connected to the rear end of the rod to oppose turning movement of the rod and claw.
